Vegan Chocolate Avocado Cake

I have a vegan friend whose birthday was a few weeks ago... so I made a vegan cake.  Didn't get around to making any frosting for it but the cake itself turned out well.  As you can see, everyone dug in before a picture could be taken.  I tweaked the original recipe a little.

Ingredients:
3 cups all-purpose flour
6 tablespoons unsweetened cocoa powder
1/2 teaspoon salt
2 teaspoons baking powder
2 teaspoons baking soda
2 cups granulated sugar
1/4 cup vegetable oil
1/2 cup soft avocado, well mashed, about 1 medium avocado
2 cups brewed coffee
2 tablespoons white vinegar
2 teaspoons vanilla extract

Directions:
Preheat oven to 350 degrees F.
Use oil to grease a 9 in pan. Set aside.
Sift together all of the dry ingredients except the sugar.  Set aside.
Mix all the wet ingredients together in a bowl, including the mashed avocado.
Add sugar into the wet mix and stir.
Mix the wet with the dry all at once, and mix.
Pour batter pan.
Bake for 30 to 40 minutes, until a toothpick inserted comes out clean.

I powdered the top with confectioner's sugar and cocoa since I didn't have time to make frosting.
Turned out surprisingly soft and moist!
